It's spangly cos it can be and I completely understand the dilemma of trying to figure out why and how a subject should have spangle attached to it. Lovely bokeh shot and the little hexagons of your lens shape are fabulous. How did you suspend the onion there? Was there a bit of cotton that we no longer see? I was also trying to figure out how to get an onion into my shot, but spangly didn't cross my mind, so I went with green brocolli instead. Very nice work with your lighting.
